Ratio Tape Diagrams: Given the Difference — Easy Worksheet 2

Grade 6 · Whoobee    Name: ____________________   Date: __________

Use the tape diagram. Find the value of one box first, then answer the question.

How to solve

The difference fills the extra boxes in the longer tape. Divide the difference by the number of extra boxes to find the value of one box. Then multiply: an amount = its number of boxes × the value of one box. For a ratio of 4 : 5 with 3 more dogs than cats, 1 extra box is 3, so there are 4 × 3 = 12 cats, 5 × 3 = 15 dogs and 27 animals.

Example
